KAYAK SAILING: WEST COAST

HOLA TITAN!

Mike Trask, Titan occidentalis, Fernie, BC

Titanites occidentalis, the second of these giant ammonite fossils recovered at Coal Mountain near Fernie, British Columbia.

The first was about one-third the size and was identified as Lytoceras, a fast-moving nektonic carnivore. This specimen, found in 2004, is significantly larger and relatively rare in North America. With no ruler of an appropriate size, you can see Mike Trask sitting in for scale.

It has been identified as a Titanites occidentalis, (Western Giant), the second known specimen of this extinct fossil species. The first was discovered in 1947 in nearby Coal Creek by a British Columbia Geophysical Society mapping team.

Titanities is an extinct ammonite cephalopod genus within the family Dorsoplanitidae that lived during the upper Tithonian state of the Late Jurassic, some 152 to 145 million years ago.

In the summer of 1947, a field crew was mapping coal outcrops for the BC Geological Survey east of Fernie. One of the students reported finding “a fossil truck tire.” Fair enough. The similarity of size and optics are pretty close to your average Goodridge.

A few years later, GSC Paleontologist Hans Frebold described and named the fossil Titanites occidentalis, after the large Jurassic ammonites from Dorset, England.

The name comes from Greek mythology. Tithonus, as you may recall, was Prince of Troy. He fell in love with Eos, the Greek Goddess of the Dawn. Eos begged Zeus to make her mortal lover immortal. Zeus granted her wish but did not grant Tithonus eternal youth. He did indeed live forever, aging hideously. Ah, Zeus, you old trickster.

It is a clever play on time placement. Dawn being the beginning of the day and the Tithonian being the dawn of the Cretaceous.

Clever Hans!

KOALA: BABY JOEY

Koala, Phasscolarctos cinereus, are truly adorable marsupials native to Australia. These cuddly "teddy bears" are not bears at all. Koalas belong to a group of mammals known as marsupials. 

Fossil remains of Koala-like animals have been found dating back 25 million years. Some of the relatives of modern koalas were much larger, including the Giant Koala, Phascolarctos stirtoni. 

It should likely have been named the Robust Koala, instead of Giant, but this big boy was larger than modern koalas by about a third. Phascolarctos yorkensis, from the Miocene, was twice the size of the modern koalas we know today. Both our modern koalas and their larger relatives co-existed during the Pleistocene, sharing trees and enjoying the tasty vegetation surrounding them.

CAVE BEAR

JELLYFISH: DANCERS OF THE DEEP

This lovely ocean dancer with her long delicate tentacles or lappets and thicker rouched oral arms is a jellyfish. 

Her brethren are playing in the waters of the deep all over the world, from surface waters to our deepest seas — and they are old. They are some of the oldest animals in the fossil record.

Jellyfish and sea jellies are the informal common names given to the medusa-phase or adult phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria — more closely related to anemones and corals.

Jellyfish are not fish at all. They evolved millions of years before true fish. The oldest conulariid scyphozoans appeared between 635 and 577 million years ago in the Neoproterozoic of the Lantian Formation, a 150-meter-thick sequence of rocks deposited in southern China. 

Others are found in the youngest Ediacaran rocks of the Tamengo Formation of Brazil, c. 505 mya, through to the Triassic. Cubozoans and hydrozoans appeared in the Cambrian of the Marjum Formation in Utah, USA, c. 540 million years ago.

I have seen all sorts of their brethren growing up on the west coast of Canada. I have seen them in tide pools, washed up on the beach and swam amongst thousands of Moon Jellyfish while scuba diving in the Salish Sea. Their movement in the water is marvellous.  

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, jellyfish are known as ǥaǥisama.

The watercolour ǥaǥisama you see here in dreamy pink and white is but one colour variation. They come in blue, purple, orange, yellow and clear — and are often luminescent. They produce light by the oxidation of a substrate molecule, luciferin, in a reaction catalyzed by a protein, luciferase.

Hiking in BC, both grizzly and black bear sightings are common. Nearly half the world's population, some 25,000 grizzlies, roam the Canadian wilderness.

Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their very large descendents. An average Grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg). This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head. It is one of the largest grizzly bears ever recorded.

TRILOBITES

Trilobites — in all their many wonderful forms — lived in our ancient oceans for more than 270 million years. The last of their lineage went extinct at the end of the Permian, 252 million years ago.

WEASEL: MUSTELA

Weasels are mammals of the genus Mustela of the family Mustelidae. The genus Mustela includes the least weasels, polecats, stoats, ferrets and mink. Members of this genus are small, active predators, with long and slender bodies and short legs.

CHILKAT ESTUARY

 

WIDGEON ESTUARY

Interested in getting out on the water? Consider an easy day paddle or overnight to Widgeon Estuary. The paddling is easy. You can do the trip via kayak or canoe and stay for the night or do it as a day trip. There are spots all along the river. You can also camp near the base of the trail to the falls.

From Trail Peak:

There is nothing better than to cruise flat water with rippling reflections of big snowy mountains cascading off your bow.

The estuary of Widgeon Creek at the south end of Pitt Lake at Grant Narrows is the perfect place to enjoy this sensation.

If you like quiet peaceful waterways teaming with bird life this is the place to go for the whole estuary is a protected bird sanctuary. After making the 300m crossing of Grant Narrows, expect to see tons of waterfowl and other species from herons to Harlequins that make this area their habitat. You might even see a fleeting glimpse of muskrat or beaver if you are lucky.

If Widgeon Creek is high in the spring or early summer you can paddle quite a distance up under lazy overhanging branches draped in moss and lichen. Huge lush ferns and skunk cabbage line the shoreline in the marshy areas and neat little gravel bars are gathered in the bends of the creek. When you are there you will be amazed that you can be so close to the city yet so far away.

A campsite is located near the west end of the estuary if you want to stay longer. This is probably best to do in the shoulder season when it isn't so busy. If the water is high more secluded sites are located up the river.

CINQUE TERRE: LIGURIAN COASTLINE

Riomaggiore or Rimazuu in the local Ligurian language is a lovely seaside village that can trace its roots to the good taste of Monks who settled here in the early thirteenth century.

Here, great wine is produced and consumed along with a huge variety of seafood, figs, olives, capers and Limoncello in the wee restaurants and bars along the Via Colombo that look out onto the Gulf of Genoa.

Inspired by the praise of Dante, Petrarch and Boccaccio, I had the great pleasure to venture there with my friend, Guylaine. Drawn to the picturesque beauty of the Liguria region, ancient vineyards and the irresistible "photo a moment" scenery, we traveled from village-to-village, all along the Cinque Terre.

Liguria remains one of the wildest parts of the Ligurian littoral east of Genoa. The coastline is home to incredibly complex and exciting geology. It is composed of the Maritime Alps in the west and the Ligurian "nappies," continental margin ophiolities, of the Apennines in the east.

Along the coast, the north-northwest convergence of the Alpine orogeny gives way to the active east-northeast convergence along the Apennines. All of this tasty geology can be observed while walking from town to town from Riomaggiore through Manarola, Corniglia and Vernazza. We stayed in Monterosso al Mare during our visit, meeting up with friends and then visiting them in their home city of Milan. If one is lucky enough to be invited as a guest, the geology of the Via deli'Amore is true to its name sake and well worth the trip.

In my mind's eye, thinking back on the experience, I picture stormy seas, colorful rowboats, sheer cliffs and exotic meals of black squid pasta washed down with Albarola.

STAWAMUS: ENSHROUDED CHIEF

BOWRON BEAUTY

Yellow Lily line pathways and float in the cold, clear lake water. Somewhere I read a suggestion to bring a bathing suit to the park, but at the moment, I cannot imagine lowering anything more than my paddle into these icy waters.

To reach the west side of the paddling route, we must first face several kilometres portaging muddy trails to meet up with the Isaac River and then paddle rapids to grade two.

BONOBO BEBE: PAN PANISCUS

DIPLOGRAPTUS: GRAPTOLITES

Diplograptus floating in Cambrian seas. These colonial animals are known from Middle Cambrian to Lower Carboniferous fossils. The name graptolite comes from the Greek graptos for written and lithos for rock — written on the rock.  And they do look a bit like scratches or calligraphy, but more so like primitive plants. I confess that when I found my first graptolite fossil, I had assumed this was a plant group, then looked them up and low and behold... aquatic sea animals!

TURTLE ISLAND: NORTH AMERICA

Turtle Island

MEGATHERIUM AMERICANUM

In 1788, this magnificent specimen of a Megatherium sloth was sent to the Royal Cabinet of Natural History from the Viceroyalty of Rio de la Plata.

The megaterios were large terrestrial sloths belonging to the group, Xenarthra. These herbivores inhabited large ares of land on the American continent. Their powerful skeleton enabled them to stand on their hind legs to reach leaves high in the trees, a huge advantage given the calories needed to be consumed each day to maintain their large size.

Avocados were one of the food preferences of our dear Giant ground sloths. They ate then pooped them out, spreading the pits far and wide. The next time you enjoy avocado toast, thank this large beastie. One of his ancestors may have had a hand (or butt) in your meal.

In 1788, Bru assembled the skeleton as you see it here. It is exhibited at the Museo Nacional De Ciencias Naturales in Madrid, Spain, in its original configuration for historic value. If you look closely, you'll see it is not anatomically correct. But all good paleontology is teamwork. Based upon the drawings of Juan Bautista Bru, George Cuvier used this specimen to describe the species for the very first time.

VIEW FROM ON HIGH

A view from on high. The Stawamus Chief, the second largest freestanding piece of granite in the world, has made Squamish one of the top rock climbing destinations in North America.

This majestic peak is said to have been one of the last areas of dry ground during a time of tremendous flooding in the Squamish basin.

Many cultures have a flood myth in their oral history and the Coast Salish people of Squamish are no exception. They tell of a time when all the world save the highest peaks were submerged and only one of their nation survived. Warned in a vision, a warrior of the Squamish nation escaped to safety atop Mount Chuckigh (Mount Garibaldi) as the waters rose.

After the flood, a majestic eagle came to him with a gift of salmon to tell him that the world below was again hospitable and ready for his return. He climbed down the mountain and returned to find his village covered by a layer of silt.

All his people had perished, but the gods gave him another gift, a second survivor of the flood, a beautiful woman who became his wife. For their gift of generosity, they had shown, the couple took the eagle as their chief totem and have honored it through generations of Coast Salish people.

BLUE JAY: KWAS'KWAS

If you live in North American, there is a high probability that you have seen or heard the bird song of the Blue jay, Cyanocitta cristata (Linnaeus, 1758).

Blue Jays are in the family Corvidae — along with crows, ravens, rooks, magpies and jackdaws. They belong to a lineage of birds first seen in the Miocene — 25 million years ago. 

These beautifully plumed, blue, black and white birds can be found across southern Canada down to Florida. The distinctive blue you see in their feathers is a trick of the light. Their pigment, melanin, is actually a rather dull brown. The blue you see is caused by scattering light through modified cells on the surface of the feather as wee barbs.

Blue jays like to dine on nuts, seeds, suet, arthropods and some small vertebrates. 

If you are attempting to lure them to your yard with a bird feeder, they prefer those mounted on trays or posts versus hanging feeders. They will eat most anything you have on offer but sunflower seeds and peanuts are their favourites. 

They have a fondness for acorns and have been credited with helping expand the range of oak trees as the ice melted after the last glacial period.  

Their Binomial name, Cyanocitta cristata means, crested, blue chattering bird. I might have amended that to something less flattering, working in a Latin word or two for shrieks and screams — voce et gemitu or ululo et quiritor. While their plumage is a visual feast, their bird chatter leaves something to be desired. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, a Blue Jay is known as kwa̱skwa̱s. 

The Kwak’wala word for blue is dzasa and cry is ḵ̕was'id. For interest, the word for bird song in Kwak'wala is t̕sa̱sḵwana. Both their songs and cries are quite helpful if you are an animal living nearby and concerned about predators.

FRESH FISH CONNOISSEURS

Ammonites were a group of hugely successful aquatic molluscs that looked like the still extant Nautilus, a coiled shellfish that lives off the southern coast of Asia.

While the Nautilus lived on, ammonites graced our waters from around 400 million years ago until the end of the Cretaceous, 65 million years. Varying in size from millimeters to meters across, ammonites are prized as both works of art and index fossils helping us date rock.
